Senior Site Reliability Engineer

RADAR•San Diego, CA

12h•$170,000 - $219,000•Remote

About The Position

RADAR runs data infrastructure across 1,600+ live retail stores, processing tens of billions of real-world events every day. We’re hiring a Site Reliability Engineer to own the reliability of that system end to end — leading incident response, running day-to-day NOC operations, and building the observability foundation that lets us catch issues before they hit a store floor. You’ll be the steady hand during a live incident, and the engineer making sure there are fewer of them to begin with.

Requirements

5+ years of experience in Site Reliability Engineering, DevOps, Infrastructure, or Production Operations, with direct incident response and on-call experience.
Experience running or actively contributing to a NOC, including shift scheduling, escalation processes, and performance metrics.
Strong hands-on experience with observability tooling (Prometheus, Grafana, Datadog, New Relic, Splunk, ELK, OpenTelemetry, or similar).
Solid understanding of SLIs, SLOs, SLAs, and error budgets, and how to use them to drive prioritization.
Hands-on release engineering experience, including CI/CD pipelines, deployment automation, and safe rollout practices like canary releases, feature flags, and automated rollbacks.
Proficient in at least one scripting or programming language (Python, Go, Bash, etc.).
Experience with infrastructure-as-code tools (Terraform, Ansible).
Experience with cloud platforms (AWS, GCP, or Azure) and container orchestration (Kubernetes, Docker).
Clear, direct communicator who stays calm and organized under pressure during live incidents.

Nice To Haves

Experience building or scaling a NOC from the ground up.
Background in distributed systems architecture and microservices troubleshooting.
Familiarity with chaos engineering and resilience testing.
Certification such as AWS Certified SysOps Administrator, Google Professional Cloud DevOps Engineer, or ITIL.

Responsibilities

Own the incident management lifecycle end to end: detection, triage, escalation, communication, resolution, and postmortem for production incidents.
Act as Incident Commander for high severity incidents, coordinating across engineering, support, and leadership until resolution.
Run day-to-day NOC (Network Operations Center) operations, including 24/7 shift coverage, escalation matrices, and shift handover protocols.
Coach and mentor NOC analysts on triage discipline and escalation judgment, and own NOC KPIs like response time and escalation accuracy.
Design and maintain observability pipelines across metrics, logs, and traces, and define SLIs/SLOs with engineering and product.
Build dashboards and alert that surface true signal from our sensor and platform data, cutting down on noise and alert fatigue.
Facilitate blameless postmortems and root cause analysis, and track corrective actions through to closure.
Maintain on-call rotations, runbooks, and escalation policies, and report on MTTA/MTTR/MTBF trends to leadership.
